I have an iframe in my code:

<iframe src ="../intro.php?text='.urlencode($line['intro']).'"
name="scroll" marginwidth="10" marginheight="10"width="500"
height="200" frameborder="1"></iframe>

where intro.php
<?=$_GET[text];?>

If $line['intro'] is 'The fox jumped' the iframe shows in both
browsers, but if it is something like:

'%3Cp+class%3D%22MsoNormal%22+style%3D%22MARGIN%3. ..'

it only shows in Mozilla.

How do I make it work?

Kind regards,
